Did audio balance disappear from the latest beta? I am sitting closer to my right speaker each side of my dual side monitor (with an UW monitor as my secondary display), and noticed that I suddenly hear all sounds from the right. I had adjusted the balance to compensate up until now, and when I went looking for it in preferences, it's just not there? (Nor in Audio MIDI Setup).

1) Can't dismiss this dialog in Settings -> Accounts

2) Still 3rd party items come before the system ones, this for me is the worst regression in version 27.

3) The language switched HUD doesn't auto-dismiss in many apps – still. This has been an issue for maybe 2 years now, if not more...

Has anything changed about the option to turn off AI yet? I switched to VM for beta so I can't verify. Can't really afford running it like usual since it effectively doubles the OS size.

Apple Mail in macOS 27 has a new Formatting Bar design with Write with Siri.

Storage for macOS & System Data has increased slightly here.

macOS reports 30.08GB but somehow says Apple Intelligence is at 31.3GB (was 29GB)

System Data is currently at 33.43GB (was 30GB)

So about 65GB just for the OS and it's files. Sure glad I opted for the 512.

Hope these values will decrease by the time the final comes out, but I'm skeptical.
That’s freaking insane. Especially with their obscene pricing on anything above 256. Can you delete AI again?

there's no pan slider when you're using most usb interfaces (ie the scarlett, or, apparently, the Mi Monitor. if you switch to the mac mini speakers, it will show up. check that first, or check the app you're listening to. or is there an option in the monitor? something is causing that...

Nope - Not for me:

I play my sound through the headphones jack to a Fosi amplifier:

I can't change the default font / text size in Apple Mail, keeps reverting back, anyone else?
Yes, they're upgrading the Formatting Bar, see:


 
It doesn't look like you can delete AI in the beta. Hoping we can turn off / delete AI in the release but I'm not holding my breath on that.
It’s a release candidate so it’s not a planned feature. Maybe if we’re loud about it they’ll change something

But my Mac mini is constantly running out of storage space already on Sequoia. I’m really mad that I’m going to have to skip another version of MacOS. I was looking forward to Tahoe

Maybe try SFX output device from the Scarlet Solo to Studio Display, and switch the output device to something else and back again. Looks fine on my system.

Hi everyone,

I'm currently running the latest macOS 27 beta. With each new beta release, I've noticed that app compatibility and overall stability have improved, which is great.

However, I still have the feeling that the operating system itself has gradually become slower. Right now, it feels noticeably sluggish at times, even though I'm using a MacBook Air M3 with 24 GB of RAM.

Once the final version of macOS 27 is released, I'm thinking about doing a completely clean installation:

* boot into Recovery,
* erase the internal drive,
* install a fresh copy of macOS 27,
* then restore all my data, apps, and settings from a Time Machine backup.

Since I shouldn't lose any data, do you think this is worth doing? Has anyone experienced a noticeable improvement in performance or overall system responsiveness after a clean install followed by a Time Machine restore, compared to simply updating from the beta to the final release?

I'd really appreciate hearing your experiences and recommendations. Thanks!

That's what I did, clean install, I find it is very quick on M4 with 24GB.
